SPECIFICATION forming part of Letters Patent No. 529,175, dated November13, 1894.

Application filed June 30,1882. SerialNo. 438,518. (Nomodeh)PatentedinEnglandApriTZO,1891,1To. 6,784, and in Belgium March 16,1892,110. 98,851.

To all whom it may concern.-

Be it known that- I, JAMES I-IOGARTH, miller l and corn merchant, asubject of the Queen of Great Britain and Ireland, of West Mills,Kirkcaldy, Fifeshire,Scotland, have invented certain Mechanisms forTesting and Recording the Properties of Flour, of which the following isa specification.

Patents have-been obtained for said invention in Great Britain, No.6,784, dated April 20, 1891, and in Belgium, No. 98,851, dated March 16,1892.

This invention has reference to and comprises certain improvements uponthe means .and appliances used in my system of testing and recording thecharacteristic properties of flour described in the specification of myPatent No. 474,636, dated May 10, 1892, and has mainly for its object tosimplify and improve the construction and action of said appliances andrender them more beneficially useful; and in order to enable othersskilled in the art to which my invention relates to understand how itmay .be carried into practice, I have hereunto appended explanatorydrawings in which the same reference letters are used to indicatecorresponding parts in all the figures where shown, and so far aspossible to corresponding parts and their letters of reference in thespecification of the said former patent, so that many of these partswill not herein require to be particularly described.

Figures 1 and 2 are a sectional elevation anda plan, and Figs. 3 and 4transverse sections taken near the lines 33 and 4-4 respectively ofFigs. 1 and 2 illustrating an improved simplified form of flour testingmachine; and Figs. 5 and 6 show front and end sectional elevations of amodified form of a flour testing machine. Figs. 7 and 8 show front andend sectional elevations of mechanism used for feeding water to thekneading machine, and Fig. 9 shows a detached end elevation of theindicating dial mechanism. Figs. 10 and 11 show sectional elevations ofwater feeding mechanism, and Fig. 12 an elevation of a portable parallelrodused for displacing thewaterduringthetestingoperations. Figs. 13 and14 are a front elevation and plan of the kneading mechanism. Fig. 15 isa sectional elevation of a modified form of kneading machine, and Figs.16 and 17 are a side section and end view of the diagram barrel andfittings. Figs 18 and 19 show side and plan Views, and Fig. 20 an endview of recording mechanism. Fig. 21 is a sectional elevation of animproved form of dynamometer.

Referring to Figs. 1 and 2 the improvements consistfirst'in dispensingwith a separate diagram cylinder F used in my said former patent, andconverting the dynamometer D into a combined long diagram cylinder F anddynamometer D, fitted preferably in its one end as shown in Fig. 1.Either the bevel or the spur gear constructions describe 1 in referenceto Figs. 6, 7, 8, and 9 respectively of the specification of said formerpatent the latter of which I have shown here as fitted in the one end ofthe cylinder F might be used. This cylinder F, Figs. 1 t0 4, isoscillated through the dynamometer D, the first and second motion shaftsO, 0' being rotated loose in pillow blocks A A In carrying thisarrangement into practice, I mount the whole on a light rectangularhollow plate frame A preferably secured on the top of a wooden openframe Z, of a convenient height off the floor Z, for the operator towork the machine, as seen more particularly in the end section Fig. 3.On one end of the frame A I mount the kneading machine A, by its endbracket A, to the pillow block frame A A screwed direct to the one endof the plate frame A The bearing block A carries one boss end F, of thediagram cylinderF, which also answers as the end journal bearing of theshaft 0, which drives the spindles a a of the kneading machine A. Theother end of thisshaft O is carried in the inner boss D of the case ofthe dynamometer D and secured to the internal toothed Wheel d of thedynamometer D. The small pinion dof the dynamometer D, is secured on theinner end of the first motion shaft 0, rotating loose in the end boss Fof the cylinder F. This first motion shaft 0 is carried in the bearingpillow blocks .A A", projecting up from the end standard piece A securedto the other end of the base plate A the shaft 0 being provided withfast and loose pulleys C C The adjustable helical spring E, as shownmore particularly in ISO Fig. 3, is here mounted in a vertical tube Dseeu red at D to the frame A and the end E of the spring E is secured tothe lower end D of the tube D by an adjustable nut E. The other movingend E of the spring has one end of the cord D attached to it which cordis carried up and passed round and attached to the cylinder F. Thuswhile the first motion shaft 0, is driven at a regular speed the diagram cylinder F is turned or oscillated more or less according to thepower taken to drive the kneading machine A.

The marking pencil e, Figs. 1 to 4 and 20,

travels at a slow uniform rate of speed longitudinally across thediagram paper X, X by means of a screw spindle fcarried in bearingblocks A A secured to the bed plate A, the block A being formed on thebracket A. The spindle f may be driven by a bevel wheel f and pinion fthe former secured on the end of the screw shaft f, and the other on atransverse spindle f which is carried in an eccentric bush bearing f 7mounted in the bracket A. This bearing f is turned by a handle f 3 toput the wheels f and f into or out of gear with each other. The otherend of the spindle f 2 has mounted thereon a screwwheel 0' gearing intoa screw 0 on the first motion shaft 0 so as to drive the screw spindle fat a slow uniform rate, and thus move the pencil e parallel to the axisof the dynamometer cylinder F across the lines y y on the divided paper,secured on the cylinder F. This would give line diagrams with the zeroline at O O, the lines varying according to the stiffness of the doughand power required to drive the mixer A. The cord D and spring E areconnected tangentially diroot from the dynamometer D, or cylinder F,without the separate diagram barrel and its gearing, required in thearrangement described in the specification of the former 'patent.

The pencil e is carried on the upper end of a spring blade e (Figs. 1,2, and 4), having its lower end secured to a slow moving side bracket eworking in a long planed guide e in the bed plate A, as seenparticularly in Figs. "2 and/l.

- In Figs. 18, 19 and 20 is shown a slight modification in which thespring blade 6' is re placed by a weighted lever e". The upper arms ofthis bracket e Figs. 2, 4, 18, 19, and 20 are steadied by bush eyes onthe outer circumference of the screw of the spindie f and a screw bushe, to work into this thread is mounted between these arms of the brackete on an eccentric spindle a, with a small weighted handle 0 on one end,which when turned in one direction keeps this bush always into gear withthe screw thread of the spindle f. Referring to Figs. 2 and 4, thistraversing bracket e carries a lateral horizontal index plate 9, with anopen recess 9' in it fitted with a sheet of mica or glass. In line withthe pointer e, across the mica or glass, a hair or fine wire 8 isstretched and tightened up by the pinching screw at 1 to pass over oneor more fixed or adjustable divided scales 3', s 3 mounted on the bedplate A just below the traversing plate 9, g to set the pencil e tostart forming the graphic diagram at zero on these'scales and the paper,and by the hair line 3 read on the scale the space traversed and timetaken by the pencil, and the quantity of water used, as will hereinafterbe described. Thus in this arrangement, Figs. 1 to 4, it willbe seenthat the diagram paper X which is mounted by india rubber bands X, orother equivalent, at its ends to the cylinder F, requires to have itswide equidistant division lines 3 y formed on the paper in thetransverse direction round the cylinder F at right angles to its axisstarting from the zero line 0 0' on the paper, which indicates the timetaken to form the diagram, and also the water added to the sample offlour being treated in the mixer A, during that time, while the pencilis moving at a regular speed parallel to the zero line 0, 0 across theselines y 1 While the closer equally divided lines at, m-are or may beformed on the diagram paper equidistant from the parallel to the zeroline 0, O and axis of the cylinder F, and indicate the varying powerexerted while the pencil e is forming the undulating graphical diagramacross these lines by the varying oscillation of the cylinder F. Theselines and divisions y, y and as, a; may or may not be first put on thepaper to suit the scales and tables it is determined to work the machineand all the samples of flour upon, as described in my said formerpatent, as plain paper may be put on the moving barrel or surface, andthe zero lines or points only put on the paper at starting by the pencile itself; and have the last or maximum or any desired intermediate ofthese time and pressure lines put on by the pencil c after finishing thediagram according to the scale used as say .9 which is shown as dividedto indicate the number of cubic centimeters of water added regularly tothe sample of flour in the mixer A, as say forty grams during the timethe pencil e and index lines are traversing to any division on the scales up to thirty-five or forty centimeters.

The scale s is or may be divided to indicate the percentage of waterrequired to be added to the sack of flour, and scales 8", in like mannercan be divided to indicate the number of loaves of adesired fixed weightto be obtained from the sack of Hour of any particular sample of flourthat may be taken or indicatedby the scales 8 used; but of course otherscales may be used, and tables may be made out and printed for useinstead of the scales 5 .9 but whichever are used they must be made outfrom tested experience gained from the form of and power and maximumpressures indicated by the diagrams and which gives the relativequalities of the flours as to the gluten and starch in them.

Another improvement consists in various simple arrangements of thefittings in connection with the vertical 'parallel cylinder of water fordelivering a uniformquantity of water from same and feeding it to thedough mixer A, and sample of flour in it, during the time of taking thediagrams. One way of doin g this consists in mou ntin'g the parallelmeasuring cylinder B, to movenvertically within a stationary steadyingbracket B screwed to the sole plate A (Figs. 1,2, and 3). This cylinderB has an open funnel filling mouth B at top, and has its lower endconnected at B to a small rubber or other elastic tube b, which tube 6'has its other end connected to the lower end of the stationary smallmetal tube b which supplies water to the kneading machine A, thiselastic moving tube 1) acting as an inverted U-shaped siphon, as seenparticularly in Fig. 3, the upper delivery end b, of the tube 1), alwaysdetermining the height of the water in the moving cylinder B. Thecylinder B is moved upward at a uniform rate from its lowest positionshown in Fig. 1, when filled with water at the filling mouth B todeliver the water regularly therefrom. This upward movement is made byforming a toothed rack B Figs. 1 and 2, on its one side, actuated by apinion B so mounted on a shallow spindle or sleeve 12 carried on adriving spindle b rotating in bearings in the standard B, as to bedriven by the spindle 22 The bevel or face wheel 12 on one end of thespindle b is actuated bya small pinion at f on the overhung end of theslow motion screw shaft fr The water cylinder-B is thus raised anddelivers the water from the pipe b, b into thedough mixer slowly and ata uniform rate. The screw spindlefis turned to move the pencil e in thedirection of the arrow across the cylinder F in Fig. 2. A hand lever bfulcrumed at its lower end 12 is connected to a grooved clutch ring I)at the center by pinching screws; and this clutch slides on the squaredend of the spindle b and takes into the hollow spindle of the pinion Bso as to engage or disengage the pinion B and the spindle b, as thelever b is shifted in either direction.

In some cases the cylinder F has a tendency to recoil suddenly backwardwith the power of the helical spring E when the power required to drivethe kneading machine A is suddenly released. To prevent this shock tothe cylinder F, and its overrunning the action of the spring E and thecord D, by one ararrangement as shown in Figs. 2 and 3, I mount a stopbracket h on one end of the cylinder F over the stem h of a helicalspring k mounted in an adjustable cylinder case It secured at h to thebase plate A or a piston and air cylinder could be used instead of thespring k which arrangement stops the cylinder F gently and prevents thisover recoil. Another which the cord D of the spring E, is wound roundthecylinder F and in securing the lower end of the cord H to anadjustable screw spindle H passed through a fixed rubber or otherelastic ring H with adjustable hand screw nut H below. This rubberelastic ring H acts to prevent this over back recoil of the cylinder F.

Instead of using a spiral, helical, or coiled spring E, to act againstthe power of the dynamometerD to give approximately divided distances onthe graphical diagram paper, proportionate to the force in poundsexerted in mixing the dough, and indicated by the dynamometer asdescribed in reference to the previous figures hereof and in thespecification of the said former patent, by further improvements Iaccomplish this more accurately by improved arrangements of anaccumulative weight or weights. 7

Referring to Figs. 5 and 6, these show views of one of my flour testingmachines, analogous to that shown in Figs. 1 and 2, but as fitted withan arrangement of improved Weight levers. This arrangement consists inmounting on the frame Z, below the sole plate A a cylinder K andattaching a cord or preferably a chain D wound round the barrel F, to aform of piston, K working in the cylinder K (which cylinder is a littlelarger in diameter than, the piston) as indicated in dotted lines inthese figures. This cylinder K would be open at the upper end and closedat the lower end to act as a steadiment and air cushion forpreventingjar in the working of the piston and cord while the differentstrains were on it. A cord or chain D from the lower side of this pistonK would pass through a small hole in the bottom of the cylinder K,tangentially down to and round an oscillating grooved quadrant K mountedon a transverse boss and spindle K quadrant K 'is provided with radialarms or webs leading down to a weight K mounted on the quadrantbelow thefulcrum spindle K ,in its normal inactive zero position as shown in thisposition in the figures. The chain D would preferably be carried roundand up the back web or arm of the quadrant K and secured to a bracketnear the fulcrum by an ad j ustable small crew spindle K and securingjam nuts to bringall to their normal zero position for starting thediagram on the barrel F of the dynamometer D.

The grooved quadrant K might be formed in various ways as by turning thesegmental web of the quadrant and mounting or securing on its sidesegmental plates K to form the groove for the chain D and the boss ofthe quadrant would be mounted on a steel spindle K mounted to oscillateon antifriction rollers is, carried on studs in brackets 70 secured tohorizontal bars Z of the frame Z; or as shown in Figs. 7' and 8, thespindle K of the difierential weighted segment K might be mounted onfine steel centers of screw studs k screwed into brackets 10 in theframe.

Z, and have jam nuts it The \Vhen the machine was started and the doughincreased in stiffness, the dynainometer D would wind up the cord andturn the quadrant and weight up, the weight always increasing as it rosefrom the normal position below the fulcrum toward the tangentialposition of the cord under the cylinder as indicated by the dotted linesK K in Fig. 5 but by preference the quadrant K would be made of such asize that it and the weight K and chain D would not require to turn morethan sixty degrees upward from the vertical position so as to giveapproximately equal distance of leverage for equal pounds of pressure ofincrease in weight. A cord H, Fig. 6, is preferably wound round agrooved pulley 1-1 on the diagram cylinder F in the opposite directionto that of the said weighted chain D, as before described, and have ascrew spindle H at its free end passed through a fixed bracket or partof the frame Z with adjustable securing nuts H on it, either with orwithout an india rubber or spiral spring H at its end, as shown in Fig.3, below the bracket, to act and maintain the barrel or dynamometer atits said normal zero position, and check the recoil action of the weightand quadrant. This spring would come into action as the weight K on thecord D and the quadrant leverK fell toits normal lowest zero positionand prevent any sudden jerk of the weight and barrel in their backreaction to this position and this arrangement would be suitable for anyor allot the accumulative weigh ts or the springs; or this weightedlever K might come back against a stretched rubber disk or cushion I-Isecured to the side of the frame Z.

Instead of using a chain D, a toothed segment K may be mounted round theperiphery of the quadrant K as shown in Figs. 7 and 8, and this toothedsegment K works up through a slot in the bed frame Z of the machine, andgears into a corresponding toothed wheel K", on the case of thedynamometerD or on the second motion shaft 0 actuated through thepinions of the dynamometer. This arrangement is very suitable for thesimple arrangement of attaching the dynamometer direct to the spindle Oof the dough mixing vessel A, without a separate indicating diagrambarrel, and suitable for being driven by a crank handle 0 on the spindleC, of the dynamometer as shown instead of the belt pulleys C 0 of theformer arrangements; and a fixed radial pointer z may be attached to oneof the bearing brackets A or other fixed part of the frame, and have thedivisions of pounds shown at 2, out or indicated on the radial end ofthe dynamometer barrel D, or on its outer periphery at one side as shownin the detached end view Fig. 9. In

Figs. 7 and 8 is also shown part of the mechanism for anotherarrangement for feeding the water to the kneading machine A. In thisarrangement a toothed wheel '6 is turned by a pinion t on the firstmotion shaft 0 of the dynamometer D, and is made to turn a screw nut ion the screw spindle i mounted on the outer end of a liquid tight pistonB working in a bored steel or other metal cylinder B filled withmercury, the. cylinder I3 as well as the screw end of the spindle andthe nut, being carried on bracketsat B in the axial line of thecylinder, The inner end of the cylinder 13 is fitted with averticalstuffs ing box B and parallel small glass tube 13 for containing wateron the top of the mercury. This tube B is filled by. a small funnel B atthe top of the tube, which a little below the top has a delivery branchb, b for delivering the water into the vessel of the dough mixer A; andas the piston 13 is regularly and slowly screwed into the cylinder B themercury will rise upin the glass tube B at a uniform rate and deliverthe water also uniformly into the dough mixer A. The glass tube B isdivided and marked lineally into inches or fractions of inches on oneside, and the rise of the surface level of the mercury will show theamount delivered during any period of the regular turning of themachine.

Fig. 10 shows an arrangement of the parallel vertical water cylinder andits fittings, in which the measuring cylinder B is mounted toreciprocate water tight (by a stuffing box 13 at its lower end). on asmall fixed internal parallel tube B secured at its lower end B to thesole plate A and connected by a lateral branch and cook below thestuifing box B of the water cylinder B to the fixed tube b, b whichdelivers the water into the kneader A. The inner tube B, has small holesB near its top,through which the water flows from the outer cylinder B,as it is raised by the cord G the cord in this case being connected tothe open filler end, B, of the cylinder B to raise it. The level of thewater in the inner tube 13 is always that of the delivery nozzle 12*.

Fig. 11 shows awater feeding arrangement in which the cylinder B isshown as fixed vertically at B at its lower close end to the soleplateA, with a small nipple branch at B to which one end of the flexibleU-tube b is attached, the other end being attached by a branch nipple toa. weighted coupling B connected to the lower end of the delivery tube1), b, which in this case is made to move in parallel guides atprojecting from the side of the kneading chest A, instead of moving thecylinder B as in the first case. The upper delivery end b of this tube bis connected to the lower end of the lowering and raising cord G thiscord being wound round any pulley or cylinder driven at a uniform rateby the gearing during the taking of the dia gram and a revolution of thecylinder F, so as to lower the tube 11, b and deliver the water from thecylinder B at a slow uniform rate by the nozzle 12 into the kneader A,the level of the water fallingin the cylinder B, as the nozzle 12 islowered, or this lowering of the cord might be eflected as describedfurther on in reference to Fig. 18. Fig. 12

shows an elevation of a portable parallel rod or spindle R, which may beof any suitable diameter for insertion into any of the water cylinderspreferably of the vertical class as shown dotted in in Fig. 11 with aband and cruciform top for resting in the funnel end of these'watercylinders for varying the area and givingany regular displacement of thewater from these cylinders during the testing of a sample and taking ofa diagram.

In the casein which the pencil e is moved by a slide frame e and screw fat a uniform speed as shown in Figs. 1, 2, and 4, andas modified andshown in partial side plan and end views in Figs. 18 to 20,'one end ofthe cord G may be attached to this traversing frame 6 and broughtoveraguide pulley G, Fig. 18, with its other end attached to the lower partof the delivery water tube B to raise it direct and deliver the waterregularly from the tubes b, b into the kneading vessel A, instead of bythe rack andpinion 13 ,43 described and shown in reference toFigs. 1 and2.

As shown in Figs. 13 and 14 the screw spindle f may be elongated andhave afiner pitch screw'at b formed on it so as to move a screw bushsocket 12 formed with a lateral stud so as to actuate a parallel pistonor plunger 18 working in a stationary horizontal water supply cylinderB4 secured at B to the soleplate A so as to discharge the water at auniform rateth'rough the tube 1), b, b tothe kneading vessel A; andformed with a filler B and filling tube and tap b at the other end ofthe cylinder F, analogous to that shown in Figs. 1 and 2 of thespecification of the aforesaid patent, but actuated in this way directwithout the complicated gearing of wheels and pinions shown in thatarrangement. The diagram may be moved horizontally and the pencilreciprocate over its surface, or the diagram may be stationary and thepencil traverse horizontally and vertically over it.

As shown in Fig. 15 I construct the kneader A in the form of a deephollow vessel A, F

of cylindrical shape, with an annular series of vertical pins or bladesa projecting up from its bottom part and mounted loose bya deep eye onthe lower end of a vertical spindle L, L, working in a footstep bearingat L bolted to the main framing Z carrying the whole, the upper part Fof the vessel A which answers as the diagram barrel for taking thediagrams on, being carried by a journal boss at F, in a bracket M,projecting from the main standard M bolted to the frame Z and carryingthe driving gearing.

While the stirrer or agitator consists of a 7 disk L secured by an eye Lto the spindle L, L, and carrying a number of radial arms, preferablytwo annular rings or frames a projecting down on each side of the lowerarms a the top part L of the Vertical spindle L is carried up throughthe top journal of water to the kneading machine. The

lower part of the casing has a pulley fitted on it, to make it actinstead of the dynamometer and to which the one end of the chain D isattached,'and carried around a quadrant sector weighted lever Kanalogous to that described in reference to Figs. 5 and 6, fulcrume'd toadjustable screw stud centers at K in brackets K projecting down insidethe main frame Z, but this chain or cord D might be connected to any ofthe arrangements of springs E, described in the specification of thesaid former patent, and in reference to Figs. 1 to 4.- of thisspecification. The mechanism is made to move a pencil e and its carryingspring arm e at a uniform rate over the paper on the barrel F, thepencil being moved by a parallel traveling'nnt f working on and actuatedby the vertical screw spindle f carried in a journal and footstepbearings in the bracket f bolted to the bracket M at the top, andactuated at a slow uniform rate by a large spur wheel Z, on the spindlef and pinion Z on the upper end of the spindle L. The varying action orheights of the diagram hereinbefore described as indicated by the linesw a; are here produced by the varying action of the case A, and theweighted lever quadrant K When this arrangement is used without thediagram barrel F'a pointer may be used with an indicating dial on thetop closed end of the case A. In this case also a pointer and divisionson the end or circumference of the barrel A, may be made to indicate thepower being taken to knead the dough, and especially the maximum powertaken, in the same manner as the pointer of a steam pressure gageindicates pressure, and analogous to that shown and described inreference to Fig. 9. Instead of mounting the bosses F, F of the barrelF, as previously described, they may as shown in section and end viewFigs. 16 and 17, be mounted on antifrict-ion pulleys 70 carried in studsis projecting from the pillow blocks A carrying the axial shafts G or Cof the diagram barrel F. V The dynamometer D is improved to make it moresuitable for mounting the said gearing wheel or wheels, or scroll camsor pulleys for the wire'cordD on the'revolving axis for actuating thetoothed racks, or other equivalent of the weights of the dynamometerhereinbefore described; and this improvement consists in forming one ofthe actuating shafts of the dynamometer D, preferably the driving shaft0 hollow, while the driven shaft 0 might either be solid or hollow,which actuates the agitators of the mixing machine A,

ITO

and the hollow driving shaft C, might either be actuated by abelt pulleyor pulleys C mounted on it, or by gearing. In this arrangement,referring to Fig. 21, I mount within the hollow shaft 0, a solid shaftor spindle d having cross arms ("1 61 at its inner end carrying the axesof the bevel or spur pinions (1 d of the arrangement shown in Figs. 6and 7 of and described in the specification of my said former patent,gearing into and within or between the driving wheel d and the drivenwheel d of the dynamometer D. The inner end of this solid shaft df ihayeither be overhung at the cross arms or have a journal (1 on its extremeinner end, working into a hollow bearing in the adjacent end of thedriven shaft 0', actuating the mixer A. This solid shaft (1 wouldproject out beyond the extreme end of the hollow driven shaft 0,preferably carried on journal hearing blocks outside. On this projectingend of the solid shaft d would be mounted very conveniently a groovedpulley D for the cord D, of any of the gearing for actuating theaccumulative weights of the dynamometer.

I claim as my invention 1.
